Going from V 12.1 to version 13 needed 2 billion miles of training data. Waymo and Apollo go and Xpeng have started to follow. They are at best at 12.1 level and most experts have said the Chinese self driving systems are at Tesla FSD version 11 level. Tesla used 500,000 cars driving an average 4000 miles using FSD in 2024 to improve the AI. If another company had 5000 cars training then they would need 400,000 miles driven. This would take 4 years of cars permanently on the road with human taxi driver.
